FLAME-DEFLECTOR FOR VAPOR-BURNERS.

SPECIFICATION forming part of Letters Patent No. 314,923, dated March 3l, 1885.

Application filed December 23, 1884. (No model.)

To @ZZ 1077/0172, t may concern,.-

Be it known that I, EVAN A. EDWARDS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Flame-Deilectors for (Jil-Burners, of which the following is a specification. y

My invention relates to the plates placed above the jets of iiame in oil-burners for the purpose of breaking up and distributing the flame and mingling it thoroughly with the atmosphere.

The object of my invention is to cause a more equal distribution of the llame of the burner and to secure the effect produced by a bed of coals. This I accomplish by means of the device described herein, and illustrated in the accompanying drawings.

Figure I is a view of my improved deflector. Fig. 2 is a view of a burner provided with my invention as it appears in operation. Fig. 3 is a plan view of my improved deiiector perforated throughout with holes of a uniform diameter.

A is a plate of metal suitable for deilecting flame. B B are non-perforated portions of the deiiector, against which the jets of flame l strike.

of the deflector, leaving the greater part of the deflector solid or unperforated. Vhen such defiectors are large, so as to spread the flame over a large space, the solid or unperforated portion is correspondingly large, and the space above such portion .does not re ceive the direct force of the blaze. If the size of the deilector is diminished, the surface over which the blaze is distributed is also diminished. I remedy these defects by constructing a large deflector and perforating it throughout, except at those points against which the gas-jets strike. By this means the flame is broken up and equally distributed over a large surface, and the heat resulting therefrom produces much the same ei'ect as that caused by a bed of coals.

If the perforations are uniform in size, as shown in Fig. 3, the force of the jet causes the fiame and uni guited gas to pass up through those perforations nearest the jet with greater rapidity than through those more remote,

thus producing a, greater body of dame at those parts of the defiector. To remedy this diiliculty,I' make the perforations near the jet smaller than those more remote therefrom. By this means the flame is more equally distributed, andan almost uniform heat is secured above the entire deector. To further aid in causing the llame to be forced upward through the perforations in uniform jets, I make the under side of the deflector concave, as shown in Fig. l. By this means the flame is made to pass downward slightly in reaching the sides of the deflector, and is therefore made to force itself up through the perforations near the edge of the deflector in greater volume than it otherwise would.

It is not absolutely necessary that the vportion directly above the jet be solid, as shown in Fig. I, but it may be perforated, as in' Fig. 3, the solid portions of the plate between the perforations serving to scatter the vapor and llame and mingle the air therewith.

The perforations above the jets in such case should be smaller than those that do not receive the direct force of the jet, in order to secure the best results; but desirable yresults may be secured by perforating the entire plate with holes of a uniform size, as shown in Fig. 3. The best form of construction, though, `is that shown in Fig. I.

Having thus described my invention,what I claim isl. A ame-deilector for an oil-burner, consisting of a plate mounted above the jets of around the solid portions thereof, substandeector against which the jet strikes being tially as set forth, those perforations nearest smaler than those more remotetherefrom, for 1o Athe solid portions thereof being smaller than the purpose set forth.
